Numerous small pines in the area have appeared to have lost needles overnight. The culprit has been the redheaded pine sawfly caterpillar. The caterpillar is about one inch long and has a reddish-brown head and a greenish- yellow body with black spots.
Early stages eat only the needle ends while more mature stages return to eat the remainder. Small trees may be killed if completely defoliated or at least stunted.
Often, caterpillars will be eaten by rodents or die from diseases. Small trees may be protected by removing the caterpillars or by using Sevin dust or liquid.
